DISINFECTING DEVICE.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed January 10, 1906. Serial No. 295,465.

To all whom it may concern:

Be it known that I, JOHN ELLwoon LEE, a citizen of the United States of America, and residing in Conshohocken, in the county of Montgomery, in the State of Pennsylvania, have invented an Improved Disinfecting Device, of which the following is a specification.

My invention relates to disinfecting or fumigating devices, and especially that style wherein disinfectants, such as sulfur or sulfurous combinations are burned, and the heat evolved by the combustion of the sulfur is used for evaporating the liquid disinfectant or water in which the device is placed, so that the vapors and sulfur fumes miX and form sulfurous acid vapor.

The object of my device is to produce a simple, neat, and substantial device for the above purpose, and one that may be used over again as many times as the sulfur is replenished.

In the accompanying drawings Figure 1 is a sectional elevation of my device ready for use; with parts broken away; Fig. 2 is a plan view of the device; and Fig. 3 is a view of a modification.

Referring to these drawings, A represents the receptacle or container for the sulfur, or disinfectant composition to be burned. In the preferred form shown, this receptacle is cylindrical or cup-shaped with a flaring top, and is provided with openings at both top and oottom. Between the inner and outer cylinders, which are preferably made of metal or fireproof material the sulfur S is placed preferably in crushed or powder form. If in a cake, suitable igniting means, such as wicks IV, are provided. If the crushed sulfur be used, a few drops of alcohol or benzin will aid to light the disinfector.

The receptacle A may be detachably supported on a base B, preferably of cast metal, having a hole I) to receive the bottom stem C of the receptacle A. Holes 5 are preferably also cast or otherwise formed in the sides of the base, not only to reduce the weight, but also to provide an escape for the water that may be in the hole I) when the stem C is inserted. Around the stem 0 are holes 0 through which the liquid may rise in to the central tube or chamber A The base for the sulfur receptacle may be in one with or attached to it. In Fig. 3, for example, I have shown the base B as formed of the side walls of the receptacle A continued from below the bottom and provided with holes 5 for the admission of the surrounding liquid.

When in use, the sulfur receptacle in either form, is placed in a pan or other vessel P, and the liquid disinfectant or water L is poured in around it until the level is slightly above that of the sulfur. The liquid also enters through the holes 0 and fills the chamber A to a corresponding level. Or the sulfur receptacle and its support may be placed in the liquid already in the pan. The sulfur is then ignited and as it burns the liquid in the chamber A and immediately around the outside of the device will be turned into steam or vapor which unites with the sulfur fumes and forms sulfurous acid gas.

If, after the sulfur has burned out, the room is not thoroughly disinfected, the receptacle may be refilled with sulfur and the process continued.

I claim as my invention A device for burning disinfectants, comprising a receptacle for the disinfectant, a base having a stem upon which said receptacle is supported and a detachable pin and socket joint between said parts, said receptacle having a central chamber open at the top and provided with a port at the bottom through which said central chamber may be filled by a surrounding liquid, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.

JOHN ELLWOOD LEE.
